This process is known as starch gelatinization.
The addition of a leavening agent, such as baking soda or baking powder, introduces another critical chemical reaction. These agents release carbon dioxide gas when heated, causing the dough to rise and creating a light and fluffy texture in the final product. This reaction is known as leavening or fermentation.
Sugar, an essential ingredient for sweet cookies, also plays a significant role in the chemical transformation. During the baking process, sugar undergoes caramelization, a reaction in which its molecules break down and recombine to produce various flavorful compounds. This chemical reaction accounts for the golden color and rich taste of well-baked cookies.
The fats used in cookie recipes contribute to both the taste and texture of the final product. As the dough is heated, the fat melts and spreads throughout, coating the flour and sugar particles. This creates a tender and moist texture in the cookies, giving them a melt-in-your-mouth quality. Additionally, fats undergo a reaction called oxidation, which enhances the flavor profile of the cookies.
To ensure that the cookies have the desired structure and appearance, emulsifiers are often added to the dough. These substances stabilize the mixture by allowing the fats and liquids to remain evenly dispersed. Emulsifiers prevent the dough from separating during baking and contribute to a smooth and consistent texture in the cookies.
